본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

Claims

(A) 100 parts by weight of silane of the following general formula [I]

(B) 5 to 500 parts by weight of an organosilicon compound containing at least two alkoxy groups per molecule and at least one unit corresponding to the following average formula (II)

(C) 0.1 to 50 parts by weight of organotitanate ester: and

(D) A primer composition for adhering a silicone rubber composition to a substrate, which is composed of an organic liquid in an amount sufficient to solubilize the primer composition.

R _n S; [OOC (CH ₃ ) ₃ ] _4-n (I)

R ¹ _a R ² _b (OR ³ ) _c S; O (4-abc) / ₂ (II)

In the above formula

R is a monovalent hydrocarbon radical or a substituted monovalent hydrocarbon radical, provided that it is not alkenyl:

n is 1, 2 or 3:

R ¹ represents a hydrocarbon radical selected from the same group as R, with the exception of R ² :

R ² is a monovalent radical containing an addition-reactive or condensation-reactive functional group:

R ³ is an alkyl, aryl or alkoxyalcohol group;

a is 0 to 3,

b is 0 to 3,

c is greater than 0 and less than or equal to 4

The sum of a + b + c is greater than zero and less than four.

The compound of claim 1, wherein R is alkyl, aryl, or alkyl or aryl substituted by halogen; R ¹ is alkyl, aryl, or alkyl or aryl substituted by halogen or cyano group; Functional groups present in R ² are vinyl, aryl, epoxy, methacryloxy, mercapto, amino or N- (aminoalkyl) amino, which are bonded to the silicone either directly or by a divalent hydrocarbon radical; R ³ is methyl, ethyl, propyl, phenyl, 2-methoxyethyl or 2-ethoxyethyl; Composition (D) is a liquid hydrocarbon or a liquid chlorinated hydrocarbon.

The silane of claim 2 wherein component (B) is a silane selected from the group consisting of tetraalkoxysilanes, organotalkoxysilanes, diorganoalkoxysilanes, partial hydrolysis products of these silanes and mixtures thereof, or at least two per molecule. A composition which is a polyorganosiloxane containing silicon-bonded alkoxy groups.

The compound of claim 3, wherein R and R ¹ are alkyl; R ² is vinyl, allyl, gamma-methacryloxypropyl, gamma-glycidoxypropyl or N-beta-aminoethyl-gamma-aminopropyl; R ³ is methyl, ethyl, propyl or ethoxyethyl; a is 0 or 1; b is 0 or 1 and c is 1-4.

A compound according to claim 4 wherein component (A) is methyl tris (+-butylpyoxy) silane; Component (B) is composed of tetra (2-methoxyethoxy) silane, vinyltrimethoxysilane, n-propyl orthosilicate, gamma-methacryloxypropyltrimethoxy silane or gamma-methacryloxypropyltrimethoxysilane. Partially hydrolysate, present in a concentration of 30 to 150 parts by weight per 100 parts by weight of component (A); Component (C) is selected from tetrabutyl titanate, dibutyltinate dimer, tetrapropyl titanate and bis (acetylacetonate) diisopropyltitanium; Component (D) is petroleum benzine; Composition 2 to 10 parts by weight of component (B) relative to component (C).
